How about randomly placed "wild" pieces? Those grey pieces could be randomly placed at the beginning of the game by the software (just a couple of them). Then, for the rest of the game, either player could use those pieces as their own. They'd never change status, always usable by either player. A grey located diagonal from the corner would definately add a significant aspect to the game. :-)
